Indonesia revisits buying Kilo submarines.

Several countries operate Kilos - main users being India (pictured), China, Iran and of course Russia.

This website has looked at many Asia-Pacific submarine forces, including those of:

and http://gentleseas.blogspot.com.au/2009/06/indonesia-gets-apology-from-malaysian.html

Indonesia currently has two Type 209 (Type 1300) submarines of the Cakra Class. These are KRI Cakra and KRI Nanggala, both were launched around 1977 and entered Indonesian service in 1981. Both boats have been non-operational for long periods since 1981. Both are recorded as being refurbished in South Korea by early 2012. The refurbishment included strengthening structures and steel sheets, modernization underwater weapons and sonar systems.

Though reportedly refurbished it is unclear whether KRI Cakra or Nanggala are operational. Submarines have a limited service life of usually 30 years or less. This is due to salt water induced corrosion, expansion/contraction causing metal fatigue, other technical problems and obsolescence compared to other submarines. The latter is particularly regarding stealthy characteristics (eg. acoustic noise). So Indonesia has been casting around for replacements for her 36 year old subs.

Indonesia's non-aligned status, experience receiving Russian arms in the 1960s and a low price offer in 2007 from Russia originally suggested Indonesia might acquire Russian Kilo submarine . Presumably Russia would recoup the low selling price by padding out the deep service, upgrade and spare part costs during the Kilo's service lives.

In 2007 Russia agreed at that time to extend a $1.2 Billion line of credit to Indonesia to buy Russian weapons including two Kilos. However this offer lapsed because Russia probably could not afford to extend the credit. The 2008-2009 GFC-subprime crisis and consequent drop in the price of oil (Russia's main export) moved Russia from being a cashed-up oil boom economy in 2007 to being cash-strapped.

A June 23, 2009 article by Richard A. Bitzinger (Air-Independent Powered Submarines in the Asia-Pacific: Proliferation and Repercussions, page 3, at http://www.isn.ethz.ch/Digital-Library/Publications/Detail/?ots591=0c54e3b3-1e9c-be1e-2c24-a6a8c7060233&lng=en&id=102465 ) also indicates:

"Indonesia had once considered acquiring several Russian submarines, but this deal fell apart over infrastructure financing ([Indonesia] wanted to use Russian export credits to build a sub[marine] base, which [Russia] refused to fund)."


Note that in late 2011 it was apparent Russia had lost in Indonesia's selection process for three NEW submarines.  Indonesia announced it would buy three South Korean "Improved Chang Bogo Class" variants of the German HDW 209 design. One of the Chang Bogos would be built in Indonesia: see http://gentleseas.blogspot.com.au/2014/02/indonesia-to-build-chang-bogo-submarine.html of February 18, 2014 and 
http://gentleseas.blogspot.com.au/2011/12/indonesia-decides-to-buy-korean-made.html 

By late 2013 Indonesia was again considering whether to buy Kilos or a proposed-advanced Russian development of the Kilo called the Amur Class. On December 7, 2013 the Jakarta Post reported the following [I've bolded interesting parts]  http://www.thejakartapost.com/news/2013/12/07/ri-looks-russia-submarines-with-multi-role-missile-systems.html :

"RI [Indonesia] looks to Russia for submarines with multi-role missile systems"
Indonesia is in talks with Russia on the purchase of a number of Kilo Class submarines, as the country expands its deterrent capabilities in anticipation of future regional disputes. 

Defense Minister Purnomo Yusgiantoro said on Friday that a team of officials, led by Navy chief of staff Adm. Marsetio, would head to Russia at the end of this month to initiate a deal and assess the technical capabilities of the arsenal. 

“There is a plan for a massive build-up of our submarine fleet,” Purnomo said in a press conference after an hour-long closed-door meeting with Russian Ambassador to Indonesia and ASEAN Mikhail Galuzin.

Purnomo said he could not provide more details as the ministry was still awaiting reports filed by Marsetio regarding his planned visit to Russia. “Further to his report, we can then decide whether to buy new submarines or modernize used ones.”

According to Marsetio, Indonesia required “at least one submarine to cover each sea choke point” (a strategic narrow point of passage). 

He said in total, the country needed a minimum of 12 submarines, as laid out in the Defense Ministry’s Minimum Essential Force strategy.


The ministry refused to detail the allocated budget for the submarines. 

Between 2008 and 2013, defense spending has increased by an average 22 percent to Rp 81.5 trillion this year, according to the Finance Ministry. The budget is slated to rise to Rp 83.5 trillion next year. 

The planned submarine purchase will be in addition to the three [Chang Bogo] U-209 submarines currently being built by South Korea’s Daewoo Shipbuilding and Marine Engineering (DSME) and state-owned shipyard PT PAL Indonesia.

The three submarines will be delivered between 2015 and 2016, and will add to the existing two [HDW 209 Class. Jakarta Post wrongly said the were "Kilo Class"] submarines procured in 1978 from the former West Germany.

Purnomo said the ministry’s interest in Russian submarines was based on their advanced cruise-missile system, with which they can accurately target an object at a range of 300 to 400 kilometers. 

Submarines are known to be effective war machines that can act as a deterrent because of their capacity for stealth. 
The ministry is also considering a number of weaponry options to be fitted on the existing submarines, such as procuring the Klub-S [or "Club S "SS-N-27A" with the NATO reporting name of "Sizzler"] 
missile system, as well as fitting them with the supersonic, anti-ship Yakhont missile [aka P-800 Oniks NATO reporting name "SS-N-26 Strobile" related to Indian-Russian BrahMos] .

Indonesia has a long history of operating submarines from the former Soviet Union, now Russia. In 1967, it acquired 12 Whiskey Class submarines from the Soviet Union. 

The new submarines may well be housed at a newly established naval base in Palu, Central Sulawesi, of which only 2.8 hectares of its total 13 hectares have so far been developed.

Natural protection against extreme ocean currents is also considered to be a necessary requirement for a submarine base.


The Palu Naval Base will in the future not only serve as a forward base but also a main naval base [see more information on Palu Naval Base at http://gentleseas.blogspot.com.au/2014/01/southeast-asian-states-buying.html ]..." ENDS


COMMENT 

In any submarine purchase the cost of training and maintaining multiple crews is high. The program cost of maintenance, basing, spares and upgrades, over and above upfront purchase price, must also be considered. Some Indonesians may have visions of an Indonesian Navy operating more than 10 submarines. This may be unrealistic given the problems Indonesia has had fully utilising and maintaining the current two submarines (Cakra Class).

A similar situation exists in Australia. We can only man around three submarines of six available - but our Admirals and Defence Department wish to expand the fleet to a (probably unrealistic) twelve subs.

Indonesia increasing to three submarines from the current two sounds more likely in terms of naval budget and Indonesia's economic growth.

BACKGROUND
 -
Submarines provide a relatively inexpensive (asymmetric) way to undertake blue water tasks. Their stealth makes up for the raw combat power of more numerous blue water surface ships (which are greater in tonnage and cost). Indonesia's submarines would represent the major means to wage medium intensity (conventional) war at sea - as well as peacetime intelligence gathering/counter-piracy/counter-terrorism.

The Indonesian Navy became a separate service in 1946, after the Indonesian National Revolution (ejecting the Dutch) began. The Navy was initially stocked primarily with craft once operated by European or the Australian navies. Beginning in 1959, the navy began to acquire a large number of craft from the Soviet Union and East European nations.

In the aftermath of the abortive 1965 coup, however, the navy suffered a decline in influence within the armed forces and the nation because of suspected involvement in the coup attempt (particularly by the marine corps) and because of the navy's small size in comparison with the army.

A large portion of its vessels of Soviet or East European origin were quickly rendered non-operational owing to a lack of spare parts and lack of maintenance expertise. Until the late 1970s, the only major replacements were four frigates acquired from the United States Navy in 1974.

Since that time, the navy has embarked on an upgrading program designed to develop a balanced fleet suited to operations in archipelagic waters. The navy's mission was to act as a territorial force responsible for the patrol of Indonesia's immense coastline. The vast majority of operational ships are stationed at the main naval base at Surabaya, East Java. Whereas the 1970s saw an increase in the fleet's ship inventory, the 1980s witnessed a major effort to improve the navy's armament posture through the purchase of the Harpoon weapons system and the MK-46 torpedo. Purchase of Russian missiles would not come with the political restrictions that come with US weapons.

Structurally, the navy comprises the headquarters staff at Jakarta under the overall command of the navy chief of staff, two fleet commands (the Eastern Fleet in Surabaya, the Western Fleet in Jakarta), the marine corps, a small air arm, and a military sealift command.

In the early 1990s, naval warships generally were not deployed to a particular region but were grouped in mobile flotillas, to be dispatched where needed. One mission concerned patrolling the strategic straits through which foreign ships enter and exit the Indian Ocean, particularly the Strait of Malacca. The other mission centered on halting smuggling and illegal fishing, considered to be problems particularly in the areas near the Natuna Islands and in the seas between Kalimantan and Irian Jaya. In support of the second mission, the navy announced plans to construct a number of limited-role bases in isolated areas in the eastern and western sections of the national territory. Patrol activity also increased in connection with the flow of refugees from Southeast Asia, particularly in the area near the Natuna Islands.
-
Indonesia's main naval priorities are probably anti-smuggling, anti-piracy, refugee boat interception, and protecting territorial boundaries and undersea oil claims (eg. Ambalat) against neighbours like Malaysia. This suggests low intensity conflict patrol boats of 100 to 500 tons should represent the vast bulk of surface ships.
-
-
The most recent surface ships acquired by the Indonesian Navy appear to be:

- the Bung Tomo class corvettes - built in 2001-2002 and commissioned into the Indonesian Navy in 2014.

- the four Diponegoro class corvettes commissioned between July 2007 and March 2009, modified versions of the Dutch Sigma class.

- the six Ahmad Yani class frigates were originally launched in Dutch service in the 1960s and commissioned in the Indonesian Navy in 1986.

- four Makassar class landing platform dock ships each displacing around 11,000 tons full load and able to take 5 helicopters.

- Dated but also significant was the Indonesian purchase in 1992 of 16 ex East German Parchims anti-submarine corvettes now given the Indonesia classification Kapitan Patimura Class.


Under Indonesia's new President Joko Widodo (appointed October 2014) Indonesia is also commissioning stealth trimaran patrol craft KCR-60/KCR-40 missile attack craft also at - see August 7, 2015 update) and AS565 Panther helicopters with anti-submarine warfare (ASW) capabilities.

Indonesia Decides to Buy Korean Made Submarines


An HDW 209 Type 1400 (this particular sub, S31, is Tamoio part of Brazil's Tupi Class) in what looks like "Sepetiba" Rio de Janeiro's harbour. Indonesia's three new submarines will be similar. 
-


The HDW family tree with HDW 209 on several branches - click to expand.
-
While North Korea is undergoing a tense and hopefully predictable transition to a new "Emperor?" of the Kim Dynasty (possibly Kim Jonghe Un) South Korea has its first submarine export order. Blending reports from The Jakarta Post (December 22, 2011) (South) Korea Herald (December 21, 2011) and South Korea's Chosun Ilbo (December 21, 2011):

The Indonesian Defence Ministry and Daewoo Shipbuilding Marine Engineering (DSME) signed the contract on Tuesday December 20, 2011 for South Korea to build three submarines for the Indonesian Navy. Delivery may be in 2015-2016 with commissioning by 2018. These submarines are South Korean Improved Chang Bogo Class derivatives of the German designed HDW 209. It is inevitable that incorporated into these two submarines is technology developed for the HDW 214. HDW 214s are HDW's main current submarine for export.

The contract was signed by the Indonesian Defence Ministry's Defence Facilities Agency chief, Maj. Gen. Ediwan Prabowo, and DSME President and CEO Nam Tae-sang.

Under the contract, the two submarines built in South Korea will be in cooperation with Indonesian state-owned shipbuilder PT PAL.

Ministry spokesman Brig. Gen. Hartin Asrind told the Jakarta Post over the phone that the contract was worth US$1.07 billion.

Indonesia’s signing of a contract to procure three submarines from a South Korean company is an effort to keep pace with other countries in the region such as Malaysia, Singapore, Vietnam and Australia.

The Improved Chang Bogo Class will weigh approximately 1,400 tons surfaced and 1,600 tons submerged, be 61.3 meters long, will carry up to 40 crew members and have eight weapons tubes for 14 torpedoes, mines, missiles (US Harpoon and/or Indian BrahMos?) and other weaponry.

The three new submarines will replace Indonesia’s two old HDW 206 Cakra Class submarines; the KRI Cakra and KRI Nenggala (both launched in 1977). As submarines inevitably rust/corrode and expansion-contraction causes metal fatigue after 30 years the 36 year old KRI Cakra and KRI Nenggala are likely to be scrapped.

Other Submarine Forces (and Acquisitions) in Indonesia's Region

• Australia, 6 Australian built, Swedish Kockums designed Collins Class commissioned in 1996-2003 with 12 future Australian built "SEA 1000" Class subs for possible introduction 2030 onwards.

• Malaysia, 2 French built Scorpene Submarines KD Tunku Abdul Rahman Class commissioned in 2009 http://gentleseas.blogspot.com.au/2009/09/malaysias-first-ever-submarine-scorpene.html

• Singapore, 4 Swedish built Challenger Class commissioned 1999-2001 and 2 Swedish built AIP Archer Class see http://gentleseas.blogspot.com.au/2009/09/singapore-submarine-development.html

• Vietnam, 4 to 6 Russia built Kilo Subs to be commissioned 2015-2019 http://gentleseas.blogspot.com.au/2009/12/tentative-vietnamese-plans-to-buy-kilo.html

Pakistani Submarine Developments - Go Nuclear?

French designed Agosta 90B. The pride of Pakistan's submarine fleet.

Pakistan sees submarines as a key asymmetric counter to India’s more numerous naval forces. This follows Pakistan's last major naval exchange with India, during the 1971 war, at which time India effectively blockaded Karachi, Pakistan's only major harbor. Pakistani efforts to curtail India's naval supremacy were largely limited to Pakistan's submarine force, which was able to sink an Indian frigate.

For many years India has had an overall superiority in conventional submarine numbers (currently around 16 active boats mainly Kilo and HDW 209 developments) but India’s forces have diverse responsibilities - to cover several countries and broad sea areas. India's diverse missions might include:
- multi-mode intelligence collection off the coasts of Burma and Pakistan
- protecting India sea lines of communication (SLOC) (particularly oil), and
- preparing to interdict China’s oil routes across the Indian Ocean.

Pakistan has a total of five active diesel electric submarines These include:


- 3 Agosta 90B class submarines (PNS/M Khalid, Saad and Hamza). Hamza (see naval-technology) is equipped with the MESMA AIP. Khalid and Saad will be upgraded with the same AIP system from 2011, and

- 2 Agosta 70s (PNS/M Hasmat and Hurmat).

Pakistan also has 3 or 4 Italian-designed MG110 midget submarines for special forces insertion but perhaps also for one way suicide bombing missions in key harbours like Mumbai.

Pakistani submarine forces probably concentrate almost exclusively on India including, preparing to:

- defend the main port of Karachi;

- breakup an Indian blockade of Karachi and Gwadar

- attack shipping outside Mumbai’s large port area (representing 40% of India’s maritime trade), and

- active signals intelligence collection and possible agent dropping along India’s west coast.

These conventional roles may have remained little changed for decades but what is altering the strategic environment is India’s recent launch of its first locally designed submarine, INS Arihant along with India’s likely deployment of nuclear tipped, submarine launched BrahMos cruise missles and then K-15 ballistic missiles.

Furthermore Pakistan would wish to counter India's the nuclear capable 3M-54/Klub (or Club)/Sizzler cruise missile (further description). Russia has modified at least five of India's ten Kilo submarines to take this missile. While the missile is principally anti-shipping it can also be used for land attack out to 275km.

In response Pakistan is developing nuclear land attack missile options - perhaps in the medium term a
naval variant of the Pakistani developed Babur cruise missile. The Babur has a range of 700 km and is capable of carrying 300kg conventional or nuclear warheads - all probably sufficient for Pakistan at the moment. The problem is that Barbur is probably too long, at 7m (with a booster rocket for submarine launch) to fit in an Agosta's current torpedo tube setup and too long for vertical launch (Agosta's have a 5330mm diameter. Modification to the Agosta torpedo tubes (unless done already) and test firing are necessary - this takes time. Hence Barburs may not be the easy, rapid fix Pakistan's Daily Times hopes for .

Pakistan probably realises that modification of the Exocet and Harpoon cruise missiles already on the Agostas may offer a quicker, but only partial solution. All of the Pakistani SSKs have been equipped with anti shipping cruise missiles which could conceivably carry nuclear warheads. The main problem is lack of range and miniturisation of nuclear warheads. The three Agosta 90B-Khalid class boats Exocets (165kg warhead) and two older Agosta 70-Hasmat’s wired to fire Harpoons (221kg warhead). See comparative chart on ASMs/cruise missiles. The smaller size of the warhead may limit their yield (unless Pakistan has thermonuclear warheads available). In any case their range (Harpoon is the longer range missile of the two - at 280km) is insufficient to hit Delhi from the sea in a second (final revenge) strike scenario and it would probably be a long, dangerous voyage to hit India's east coast targets.


Pakistan is known to have conducted tests on its anti-ship Harpoons to make them more land attack worthy. These tests may have also involved range extension.
In mid-2006 the Pakistan Navy announced its requirement of three new SSK attack submarines to replace the two Agosta-70s. The French naval firm DCN had offered its latest export design - the Marlin SSK - which [is an AIP equipped development of] the Scorpene SSK, but also uses technology from the Barracuda nuclear attack submarine. However, the Pakistan Navy is said to have chosen the German [AIP equipped] HDW Type 214 submarine. During the IDEAS 2008 exhibition, the HDW chief Walter Freitag stated “The commercial contract has been finalised up to 95 per cent.”
Pakistan, perhaps for bargaining reasons, has denied that a purchase of 3 HDW boats is final. To further complicate the purchasing picture, with France due to assist Brazil to build a nuclear Scorpene Pakistan may see possibilities for future French nuclear assistance.
Pakistan would certainly be worried about India's development of nuclear submarines with nuclear missiles yet the cost and lead times for Pakistan itself to develop its own nuclear submarines would be too great. Assistance from France or even China is likely to be too politically charged from a proliferation standpoint. In any case nuclear propulsion may not be an essential requirement for 3 or 4 Pakistani submarines. Adequate medium range nuclear tipped missiles fired from sufficiently large conventional submarines may be what Pakistan wants or needs.

Therefore it will be of great interest what submarine Pakistan wants next, including subsequent diameter alterations, VLS choices or further testing of appropriately sized cruise and ballistic missiles.
